Miter & Bevel Angle Calculator
Calculate miter and bevel angles for complex cuts and polygon frames
About this calculator
The Miter & Bevel Angle Calculator helps woodworkers, carpenters, and DIY enthusiasts determine precise cutting angles for complex joints and polygon frames. This tool eliminates guesswork by calculating both miter angles (horizontal cuts) and bevel angles (vertical cuts) needed for perfect-fitting corners, picture frames, crown molding, and multi-sided projects. Whether you're building hexagonal planters or octagonal tables, this calculator ensures your cuts are mathematically accurate, saving time and reducing material waste from incorrect angles.
How to use
Enter the number of sides for your polygon project or specify your desired corner angle. The calculator will instantly compute the required miter and bevel angles for your cuts. Use these calculated angles to set your miter saw or adjust your cutting tools for precise, professional-quality joints.
Frequently asked questions
What's the difference between miter and bevel angles?
Miter angles are horizontal cuts across the face of the board, while bevel angles are vertical cuts through the thickness of the material.
Can this calculator work for irregular polygons?
This calculator works best for regular polygons with equal sides and angles. For irregular shapes, you'll need to calculate each angle individually.
What tools can I use with these calculated angles?
Use the angles with miter saws, table saws, hand saws with miter boxes, or any cutting tool that allows angle adjustments.
